I just bought a pacman last saturday and I think he was a little impacted since he hadn't used the bathroom until last night and had a hard lump on his left side. I soaked the little guy in honey water 3 days in a row for 20 minutes and he finally went last night. After soaking him in the honey water I would set him in the water bowl in his tank and he'd sit there. Last night he finally went to the bathroom in his tanks bowl after a soak in honey. Hopefully everything comes out alright for your little guy.
